Review & Installation Video

Hey, everybody. I'm Justin with americanmuscle.com, and welcome to my quick overview and install of the K&N Series 77 Cold Air Intake Kit available for your 2011 through 2014 5-liter powered F-150. If you've been watching these videos for any time now, you know what we're gonna talk about in the intake reviews. We're gonna talk materials, we're gonna talk what kind of benefits you can expect from bolting this thing up to your 5-liter truck, and then finally, we'll briefly cover the installation. And right up front, guys, for your 5-liter powered F-150, you're looking at a no-brainer job. One out of three wrenches on the difficulty meter with some more detail coming up later on.
So the Series 77 from K&N should appeal to truck owners out there looking to step into an aftermarket intake option from one of the most trusted names in the aftermarket and one that will help deliver a little bit more power and sound with or without a custom tune. But maybe the most important factor here with this particular intake, you guys can see it, right? This is definitely gonna be for the F-150 owners out there looking to add a little bit more flash or a little bit more bling underneath the hood by going with a brightly polished option as opposed to an all-black intake that seems to dominate the category.
So K&N is one of those companies that doesn't really need an introduction. They've been a dominant force in the aftermarket and are certainly one of the leaders in aftermarket filtration, and that is really well represented here on the site. They have a bunch of options for the 5-liter truck, and of course, the Mustangs as well including the Series 57, the Blackhawk option, and last but not least, the 77 that we have here on the table. All pretty similar from model to model but with minor differences.
Now, the Series 77 that we have in this video is gonna be a little bit unique in the K&N lineup and from other aftermarket intakes in the category thanks again to that brightly polished finish here. Now, in my experience, guys, there's two completely different kind of camps out there when it comes to truck owners. People who enjoy seeing all that flash and that brightly polished chrome or people who just prefer to keep things a little bit more subdued, maybe a little bit more OE in appearance and go with something that's black, for instance. This, obviously, I don't even have to tell you, right? I mean, this is gonna be for the owners out there who just prefer that chrome or a little bit more flash under the hood.
But added bling aside, of course, there are some power benefits to talk about when installing an aftermarket cold air intake like this and K&N's claiming roughly 10 horse power, 10 foot-pounds of torque when adding their no-tune required Series 77, and honestly, I think that's gonna be pretty much right on the money, guys. Don't expect massive gains when doing an intake like this without a tune because it's just not gonna happen. Instead, high single digits, low double digits is usually power for the course.
And that is one of the good things to point out too about this intake. You can bolt this thing up and go with or without a custom tune, make a little bit more power like we just said without a tune. A little more with the tune, of course, make a little bit more sound underneath the hood. And some of our customers have even pointed out picking up a small bump in fuel economy. Now, while I can't personally confirm this, it is worth pointing out and it's another reason to check out some of the customer reviews on the product page if you haven't done so already. These are guys and gals out there who have actually purchased the product, installed it, and are pounding the pavement out there and they have some real-world feedback that you should definitely check out.
But let's break down some of the individual components here with the K&N Series 77. We already talked at length about the intake tube itself but just so you know, it is made from lightweight aluminum and then polished to this bright, shiny you see here in front of me. You're also gonna be receiving one of K&N's bread and butter filters, guys. This is what they built their brand on. This is probably what they're known most for. It is washable. It is reusable and you do have to re-oil this thing from time to time.
Definitely gonna save you some money in the long run compared to those cheap paper element factory filters. You're tossing those things every 10,000 miles or less depending on their condition. Not the case with the K&N. In fact, they're saying you can reuse this thing up to a 100,000 miles before it's time to throw this puppy away and start all over again. So again, will save you some money on the long run and it will be a lot easier to know when it's time to clean this thing thanks to the open element design.
Another benefit with the open element or open filter design is the fact that you're gonna be hearing a lot more awesome noise coming from underneath the hood of your 5-liter truck. Nine times out of 10, this is a noise a lot of people enjoy and that's something you see in the customer review section. But maybe one of the best things about the K&N lineup including the Series 77 here is the price. Super affordable when it comes to aftermarket intake systems and for the brightly polished version, you're gonna be looking at the mid to high $200 price range. Far more affordable than some other options on the site which can oftentimes land from the $300 to even $400 range. Not the case here with K&N.
Well, let's switch gears and quickly talk about the installation. We're not gonna go step by step here, guys, but we'll just give you a better idea of what you can expect when it comes time to crack open the toolbox. We're gonna go one out of three wrenches on our overall scale of difficulty. This is not a difficult install so if you're not what you would consider a very mechanically inclined person, these are always a great place to start, cold air intakes. You're only gonna be looking at about an hour tops for the install time but if you've done this a few times, I'd probably say 30 minutes or less is what you're looking at here.
As far as basic tools, guys, well, again, basic is the word here. Flathead screwdriver, Philips head screwdriver, things like that including a socket set. The one kind of curve ball we might throw at you tool wise is gonna be a set of torque spits and that's just gonna help you remove the mass airflow sensors from the factory intake and get it reinstalled into the K&N here. As far as the installation process, guys, well, I like to deal with these things kind of already assembled, so remove that factory intake in the upper portion of the air box, kind of all in one piece. You can do this simply by removing it at the throttle body connection and disconnecting a few things at the air box. Don't forget about the hoses and such on the intake tube itself.
Once that is out of the way, get to work installing the new K&N in the reverse order. Again, put this thing together first out of the truck. It'll make putting it back in a whole lot easier. Trust me. Hook everything up. Your hoses, your mass airflow sensor, and you should be good to go.
As for my final thoughts on the K&H here, guys, I think the Series 77 is going to be a no-brainer for truck owners out there who want an affordable intake and still wanna grab that brightly polished finish. This thing will help you make a little bit more power. It'll definitely produce a little bit more sound. It is 50 state legal, and again, you can use it with or without a custom tune. So that is my review of the K&N Series 77 which you can grab right here at americanmucle.com.

5 Top Rated Questions

hello im looking into buying something like this. My two questions are why does it say this will not fit if I have a body lift? My other question is what is the difference from this and the black out series other than the color and price. Just trying to figure out which one I should buy thank you.

The K&N Series 77 High Flow Performance Cold Air Intake attaches both to the engine, which is mounted to the frame through the K member, and it attaches to to the body. When installing a body lift, the distance between the mounting points change, and this intake is not flexible enough to accommodate for this. The K&N Backhawk would have several minor differences in design, but the primary differences are the black powdercoat, and black filter.

My name is Blaine I was was thinking about getting one later on my truck is a 2010 F-150 with the 4.6 liter three vavle and I was wandering is this a good investment and will it mess my truck enigine up. Will it work with a two and a half inch leveling kit

What is the performance difference in the 57 and the 77?

The performance difference as per K&N's website is the 77 series will add an estimated HP gain of 15.07HP @ 4650RPM and the 57 series will give you an estimated HP gain of 16.14HP @ 4650RPM. So they are very close in performance.

Install was not difficult but the crank case vent hose did not line up well. Even rotating it up it still was tight fit. Love the sound it gives the engine. I coupled it with a Roush exhaust. My F-150 sounds wonderful. Love it. Gained 2mpg as well.

I've had a KandN CAIs in all my f150s and mustangs in the past but this is the best performance and sound I've noticed and heard of all my vehicles. I love it and if you get a complete exhaust along with it you're in for a nice treat. The two work amazing together. I had the Borla ATAK cat-back and the KandN CAI installed at the same time and talk about a head turner.
Only took about 45mins to install. Very simple plug and play.

Sure it sounds nice but kills you mpg. I installed and drove the weekend, normal driving and in city good 6 mpg drop. On the hwy at least 4 mpg drop. Even cruising on highway at 1500 rpm reading 17.7 mph best vs what I was getting with standard fram of mid 22 mpg. American trucks will not return as it was installed, they should stop putting false ratings to boost sales.

It produces a nice sound and a bit more response in acceleration, I don't think I experienced as much difference as the others because I have a 6 in lift on my truck. Only downside is that I lost .2 mpg

Before the intake I was getting probably 11.5 MPG. With the intake my MPG boosted to 14.3 and is still climbing. Highly recommend this. It sounds great performs great and your gas mileage goes up. There's no down side.
